Choosing the correct battery

The model identity on this listing is SL803 Battery Charger. Olight accessories can use similar connectors, diameters or mounting patterns while remaining model-specific, so match the complete model designation—not appearance alone—before ordering.

Before checkout, compare the product name with the model already in use and inspect the saved photographs for connector, mounting and finish details. If any part of the model designation differs, confirm compatibility before treating the item as interchangeable. Keep the model label and order record for future replacement checks. This is especially useful when the original light, mount or charging accessory is later replaced. Retain any supplied instructions so another user can identify the same configuration correctly.

Battery selection and safe use

The Olight SL803 Battery Charger is intended as a model-specific power component, not a universal substitute selected only by physical size. Match the stated chemistry, voltage, capacity, terminal arrangement and compatible Olight model wherever those details are listed above. Do not mix cells of different types, ages or charge levels in equipment that uses more than one battery.

Inspect the battery and contacts before use. Do not use a cell or pack that is swollen, leaking, punctured, wet or has damaged insulation. Charge only with a compatible charging system, keep batteries away from heat and metal objects that could bridge the terminals, and store them in a dry place.

Runtime and replacement expectations

Actual runtime depends on the light mode, temperature, battery condition and the device drawing power. A replacement battery can restore useful service, but it does not change the output modes or charging limits of the compatible product. Follow the light or charger instructions when installing and charging it.
